RICHARD J. HUTOHINGS, OF SWANSEA, SOUTH WALES.

MANUFACTURE OF TIN, TERNE, AND METAL PLATES.

' SPECIFICATION forming part of Letters Patent No. 245,723, dated August16, 1881.

Application filed April 11, 1881. (No model.) Patented in England June.26, 1876.

To all whom it may concern Be it known that I, RICHARD JAMES HuronlNGS,of Swansea, South Wales,have invented new and useful Machinery used inthe Manufacture of Tin, Terne, and Metal Plates, (for which I haveobtained a patent in Great Britain 26th June, 1876, No. 2,632,) of whichthe following is a specification.

The preliminary operation to which the plates are subjected before beingimmersed in a bath containing tin or terne metal is by fluxing them,which it has been customary heretofore to do by twooperations-videlicet, byimmersing the plates in a bath of fluxpreparatory to their being conveyed to the bath containing the coatingmetal. Now, according to this invention, the flux or preliminarygreasing pot is dispensed with and the plates, instead of being immersedin the flux or grease pot, are passed between a pair of rolls which aresituated immediately above the bath or tinmans pot.

The invention will be best understood by reference to the accompanyingdrawings, and convenient ways of carrying the same intoeft'ect are asfollows.

Figure 1 is a side elevation; Fig. 2, a front elevation, partly insection; and Fig. 3, a plan of machinery constructed according to onearrangement. A is the bath containing the coating metal. B B are thefluxing-rolls, to which rotary motion is given by the spur-gearing B, B,and U. The rolls are preferably cylindrical, to contain a supply of oil,and they are in this arrangement provided with apertures or perforationsby which the oil or fluxing agent is admitted to a porous absorbentmaterial surrounding the said rolls.

Fig. at is a part-section at one end of such a roll constructed in thismanner, drawn on a larger scale than the rolls shown in the previousfigures. B is the roll proper, made preferably of wrought-iron. tubing,and provided with perforations a. D is the absorbent materialsuch asfelt-surrounding the said roll. FE are the brackets containingthebearings for the rolls B B. The said brackets E at one end fit aroundthe driving-shaft F, and when at work are secured to the pot A by pinsor bolts b, and when these are removed the rolls can be turned back uponthe driving-shaft F, which forms a hinge, so as to leave the mouth ofthe pot open; but in some cases, when so turned back, they fit onanother potwhich contains another supply of molten metal. 0 is a hollowshaft at one end of the cylindrical roll, Working in the bush or hearingd, and at. the same time allowing of the admission or insertion of thepipe 6 from a tank or reservoir, by which the fiuxing-grease is fed tothe interior of the rolls and its supply regulated by a tap orotherwise. The pipe 6 may be of india-rubber tubing. Thesecoating-rollers are driven by spur or other gearing and simultaneouslyflux the plate, and immediately after deliver and immerse it in the bathof metal below.

Fig. 6 is a part side elevation of the wheels B B and driving-wheel Gdrawn to a larger scale.

The coating or fluxing of the plates by the before-described means (andpreparatory to their being coated with metal) has been found verysuccessful and effectual in work, as the grease or flux is applied sothoroughly and evenly and brought into such intimate contact with thesurface of the plate that any further fluxing or greasing in the courseof the coating operation is unnecessary, and the plate will take asufficient coating of metal with a less numberof immersions in the metalbaths than heretofore. Consequently the number of metal baths may beconsiderably reduced, and one apparatus of the construction shown anddescribed may be employed for two sides or setsthat is, one tinningapparatus with one pair of rolls will'produce sufficient work to supplytwo washmen or two sets or sides, one tinman supplying both sets orsides with coated plates for the further operations of washing,brushing, and finishing.

Instead of the rollers being made hollow they may be made solid andcoated with the absorbentmateriahthe flux or grease being supplied toone or it may be both rollers by a hopper above one roll.

Fig. 7 is a cross-section of such arrangement. A is the metal bath; BB,the rolls, and H the hopper.

Fig. 8 is a cross-section of another modification, but where the flux isapplied by a roller dipping in a trough containing fluxing material andsupplying one roller. A is the metal the coating-pot, of hollowperforated rolls for I5 receiving grease or flux, and an absorbentenvelope around such rolls, substantially as specified.

3. In combination with the coating-pot, the rolls for applying flux orgrease to the sheets, 20 hinged bracket-bearings for such rollers, andthe driving-shaft and gearing, substantially as specified.
